I’d like to talk about how rodents, relationships, and riding relate to overall health and wellness.

This idea comes from a nicely-written New York Times piece entitled, “Does Loneliness Reduce the Benefits of Exercise?” Here, Gretchen Reynolds reviews a few intriguing studies about how relationships may affect exercise, stress hormone levels, and intelligence. The combo caught my eye.

Anyone who pays attention to wellness knows that exercise produces more flexible arteries, more durable hearts, and leaner body shapes. These benefits are obvious, and honestly, sometimes a bit tiresome to write about.

To me, a far more interesting — and lesser known — benefit of regular exercise is that it might make us smarter. Here’s where the rodents come into the story.

As was summarized in the New York Times piece, when researchers allowed rats and mice access to running wheels they observed (a) that they all ran, and (b) those rats that did run scored better on rodent IQ tests, and actually grew more brain cells. This is a striking finding because nerve cells — unlike blood, GI and skin cells, which turnover rapidly — grow very slowly, if at all.

But that’s not the entire story. The Princeton researchers wanted to know whether the rat’s social relationships could have measurable biologic effects.

It turns out that rodents — like humans — are quite social. So social, in fact, that in these trials the brain-growing effect of exercise was blunted when rodents lived alone. Compared to rats and mice that lived in groups, those that were kept in isolation failed to grow new nerve cells in response to exercise. And importantly, isolated rats produced higher levels of stress hormones than those who lived in groups, even though both groups ran the same distance. Read more »

A trained observer is what most electrophysiologists are. And being a trained observer carries over into real life, as would the handiness of a plumber, or the strength of a brick layer, or the wordsmithing of a journalist.

Will and I drive past our house.

“Whereare we going now,” he asks in the exasperated tone of a 13 year old.

I need to take a picture.

Why?

Because middle-aged patients who’ve recently realized that their life is half over often seek clues to longevity.

Let’s take stressed-out, middle-aged patients who’ve somehow been rendered free of AF (maybe by a skillful ablation, or more likely just happenstance). Let’s also say they don’t smoke, drink excessively, have normal blood pressure, normal blood sugar, and aren’t obese. Is there anything else they can do to live longer, they often ask? Yes, I believe there is. Read more »

Years ago I had a student who repeatedly asked me how psychotherapy works. “How is it different than a conversation?”

When I think of psychotherapy, I think in terms of the talking itself as being the aspect that helps — and yes, of course it can be used in conjunction with medications. I think of it as being structured — in terms of time and place and frequency — and being all about the patient. And whether or not it’s actually discussed, some of what works is about the relationship — most people don’t get better talking to someone they despise, and the warmth, empathy, feeling listened to and cared for, well, they’re all important. And I also think of it as being a process over time. These are all parts of my definition, however, and they may not be parts of yours. Read more »
